Subject: [PATCH qemu 0/1] MAC address falls to permanent
Date: Tue, 31 Jan 2023 21:23:36 +0300 [thread overview]
Message-ID: <20230131182337.15645-1-vlaomao@gmail.com> (raw)
A bug was found with the vmxnet3 driver, after changing the MAC address
and rebooting, it falls into the category of a permanent address until
the VM is turned off. Here is log output:
-bash-4.4# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
2: ens3: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group
default qlen 1000
link/ether 52:54:00:12:34:56 brd ff:ff:ff:ff:ff:ff
-bash-4.4# ip link set dev ens3 address 33:33:33:33:33:33
-bash-4.4# ip a
